MosaicHaven is a Chrome extension designed for users to save images and text from the web into organized, private collections called havens. This visual bookmarking tool allows for seamless saving without intrusive ads or distracting feeds. Users can save content via three methods: through the toolbar icon to browse images, by right-clicking on an image, or by capturing page text. Each method provides a quick and efficient way to curate personal collections.

The extension emphasizes user control and privacy, ensuring that all saved content remains accessible only to the user. Features like auto-tagging and semantic search enhance the organization and retrieval of saved items. While the free plan allows for three havens and 50 pins, an unlimited option is available for a nominal fee. A free account is required to utilize the extension, which functions exclusively at the user's request.
